a all whom it ma concern:

Be it known tiat I, Anrrmn Noams, a citizen of the United States, residing at Trinidad, in the county of Las Animas and State of Colorado, have invented certain new and useful Improvements in Gas-Distributers for Hydrocarbon-Engines, of which the followin 1s a specification.

My invention relates to certain new and useful improvements in gas distributors for hydrocarbon engines.

The object of my invention is the construction of a multiple cylinder hydrocarbon engine in which each of the cylinders is provided with a separate intake pipe, and each of said ipes is connected to a gas distributing cham er, which chamber is in turn c0nnected directly to a carbureter, a suitable rotary valve being mounted in-the distributing c amber and serving to open up and cut off communication with the intake pipe of each of the said cylinders, whereby each of said cylinders during the intake stroke of its piston is in direct communication with the carbureter while the other of said cylinders and their intake pipes are out of such communication. As result I produce the same effect as though each cylinder were connected directly to a separate carbureter, and each carburetor so constructed and adjusted that it would give the identical mixture given by the ot er carburetors to the series.

Furthermore, by my invention, the cubical contents of each connection between each cylinder and the carbureter is substantially the same, whereby ractically identieal charges are delivered to each of the cylinders.

With these and other objects in view my invention consists in certain constructions, combinations and arrangements of parts the preferred form of which will be first described in connection with the accompanying drawings, and then the invention particularly ointed out in the appended claims.

Re erring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs, Figure 1 is a side elevation of an ordinary type of a four-cylinder four-cycle hydrocarbon engine equipped with the preferred form of my invention; Fig. 2 is a central longitudinal section of t e gas distributer shown in Fig. 1, and Fig. 8 is a. section taken on line 3, 3 of Fig. 2, and looking in the direction of the arrow.

In Fig. 1, 5 designates the cylinder of a four cylinder four-cycle engine. The number of cylinders is, however. entirely immuterial, four being shown merely for illustration. These cylinders are equipped with the ordinary inlet and exhaust valves, and o erated in the usual manner. 6 designates t e ma neto shaft, on which is shown as mounts the magneto 7 and the oil pump 8'. In the form of construction illustrated I have shown my gas distributer as connected to and driven from the magneto shaft 6, but it is obvious that it might be connected to an independent shaft driven in any desired way from the crank shaft, or it might be connected to the valve shaft. 7 designates a cylinder surrounding theshaft 6 and provided with a pair of heads 8 cl0s ing the ends of the cylinder through which the shaft 6 extends. The heads 8 are preferably provided with stufiing boxes 9, by means of which a gas-tight joint is formed between the shaft and heads. I also preferably mount ball bearings 10 of any desired type in the cylinder heads to provide suitable supports for the shaft.

The cylinder is shown as being centrally provided on one side with an inlet opening 11, which is shown as connected directly to the outlet pipe 12 of the carburetor 13 by the flanges 14, 15 formed on the opening 11 and the outlet 12 respectively, which flanges are bolted together by means of bolts 16.

From the foregoing construction it will be seen that the interior of the cylinder 7 is directly connected to the outlet of the carbureter. The cylinder 7 is also provided in its side with a plurality of outlet openings or ports 17, the number of ports provided being equal to the number of inlet pipes which it is necessary to provide to suply gas to all the cylinders of the engine. n other words with a four cylinder engine as illustrated four of these openings 17 would be required. With a six cylinder engine where the cylinders are cast in pairs only three ports would he required, whereas wit a six cylinder engine where the cylinders are cast separately six port openings would be necessary. The intake pipes 18 for the engine cy inders are connected to the ports 17, one pipe being connected to cylinder by means of the bolts 20, and pro-- vided with openings extending therethrough, said openings at one end registering with the ports I? and with the pipes 18 secured in thcother end of the openings.

I provide in the form of my invention shown a rotary valve mounted upon the shaft 6, extending through the distributor cylinder 7, said valve being so constructed as to leave the inlet opening 11 constantly open while controlling the ports 17, so that when the inlet valve of a cylinder is open onlythe port 17 which communicates with said cylindenwill be uncovered. In the form of construction shown this is effected by constructing the rotary valve in the form of two cups 21, 21, which are secured to "the shaft 6 by means of the keys 22, extending through the central inwardly extending bosses 23 of the cups, and into the shaft 6. The sides of the cups extend toward each other but their adjacent ends are separated a distance substantially equal to the width of the inlet opening 11, so that a gap is formed, and the inlet opening is always in communication with the interior of the rotary valve formed by the cups in the-distributing cylinder. This rotary valve is provided at its periphery with'openings 24, one'for each of the ports 17, and so positioned that they will register with said ports in the proper order to cause each port to be opened when the piston of its cylinder is on its intake stroke.

Fromthe construction so far described it will be apparent that ifwhen the piston of one of the engine cylinders is on the intake stroke the port 17 connected to such cylinder be opened, and the other ports 17 closed, a direct connection will be made between the cylinder whose piston is on its intake stroke and the carbureter. Also, the

intake pipes of all the other cylinders will be cut out and consequently there will be a direct suction produced by the piston upon the carburetor without the suction being weakened by having to form a partial vacuum in the intake pipes leading to the other cylinders.

I realize that considerable variation is possible in the details of construction and arrangement of parts without departing from the spirit of my invention, and I therefore do not intend to limit myself to the specific form shown and described.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

In an internal combustion engine the com-.

bination of. a plurality of cylinders, a charge receiving chamber formed with an inlet opening and a plurality of exit openings, a casting mounted on the chamber and provided with a plurality of openings, which register with the openings in said chamber, pipes communicating with said openings in the casting and communicating with the cylinders, a shaft extending through the chamber, twocup-shaped valves secured on the shaft and operating in the cylinders, the cup-shaped valves being open at their inner ends and the latter being spaced apart to provide an intercommnnicating passage with the inlet opening in the chamber, the closed ends of the cup-shaped valves fitting snugly against the inner surfaces of the end walls of the chamber, the cup-shaped valves hav ing openings arranged to supply the pipes at different periods with fuel, and means for rotating the shaft.

In testimony whereof I aflix my signature in presence of two witnesses.
